The ones I buy seem to have cracked the secret of the car battery
warranty. As soon as the warranty period is up, you can count on
them going within a couple of months.

HEy that anode rod that's supposed to do the electrolysis bit to save
the tank must actually work with the water you have. BAck where I
used to live you were lucky to get ten years on the tanks. THat
stuff was nasty. GO down to take a morning shower and see bright
orange liquid coming out of the shower head.

And that is why you should do the monthly purge. Or at least every six
months. It's not that difficult to drain a gallon out of the thing into
a bucket.

You can buy heaters with a stainless steel lining, too, rather than the
cheap glass lining. They last a lot longer, but cost a lot more. I
just went from a well to city water and I'm seeing a lot less crap coming
out when I do the monthly purge, but I'm waiting to see how that affects
the total life.
